ASME B16.5 lap joint flange are divided into two kinds: butt welded ring ASME B16.5 lap joint flange and welded ring ASME B16.5 lap joint flange. The loose sleeve flange of the butt welding ring is a movable flange, which is generally matched on the water supply and drainage accessories. When the manufacturer leaves the factory, each end of the expansion joint has a flange, which is directly connected with the pipe and equipment in the project with bolts. Function: The purpose of using the butt welding ring ASME B16.5 lap joint flange is generally to save materials, its structure is divided into two parts, the pipe part and the pipe are connected, and the head is made into the butt welding ring. Flanges are made of low-grade materials, and the pipe part is made of the same material as the pipe to achieve the purpose of saving materials. However, the disadvantage of ASME B16.5 lap joint flange is that the strength at the welding ring is low (especially when the thickness is below 3mm).
ASME B16.5Lap joint flanges are usually used in low pressure applications and are not suitable when there are high loads on the flange pair. Some types of piping require the use of ASME B16.5 lap joint flanges. For example, metallic pipe that has been plastic lining may have lap joint flanges.
Using ASME B16.5 lap joint flanges might be an option for saving costs when the piping is made of exotic materials. By using a ASME B16.5 lap joint flange, the wetted materials would consist of the exotic materials and the flange would be carbon steel. Since the flange doesn’t ever come in contact with the process fluid, it would not be affected by the fluids.
Dimensions on the ASME B16.5 lap joint flange are similar to weld neck, slip on or socket weld flanges. The backing flange has the same number of bolt holes, size and thickness of a weld neck or slip on flange.
